Specification of Letters Patent,

Patented Nov. 12, 1918.

Application filed December 20, 1917. Serial No. 208,121.

To all whom it may concern:

Be it known that we, JOHN S. WALKER and SYLVESTER N. WrLcox, citizens ofthe United. States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Garage-Heaters; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has for its object to provide an extremely simple and inexpensive, yet a highly efiicient heater for garages and the like in which it is essential that none of the air from the interior of the building shall have access to the burner; and with this eneral object in view the invention resides 1n the novel features of construction and unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawing which forms a part of this specification and in which:

Figure 1 is a vertical longitudinal section of the heater;

Fi 2 is a vertical transverse section on the p ane of the line 2-2 of Fig. 1; and

Fig. 3 is a horizontal section on the plane indicated by the line 3-3 of Fig. 1.

In the drawing above briefly described, the numerall 1 designates a subtantially flat vertically disposed casing formed of sheet metal with its bottom completely open at 2 and its top provided with-a wire screen 3 to prevent any objects from falling into the device. The edges of the screen 3 are preferably anchored 1n channels 4 formed by suitably crimping the upper edge of the casing walls. Immediately below the screen 3, a water shed 5 is provided in the casing,

suitably arched in transverse section and. having its longitudinal edges spaced from the sides of the casing, while its ends are secured to said casing. The oflice of the part 5 is to prevent the possible spilling of water or other liquid onto the parts located in the casing.

A relatively small burner box 6 of rectanlar shape is positioned. in the casing 1 and contacts with the inner. face of the 'front side 7 thereof, the front wall 8 of said burner box and the side 7 of the casing of these tubular neck 10 passes through these openings at its inner end and is provided wit an outer face of the side 7, and with an inner flange or the like 12 contacting with the inner face of the wall 8. By thisarrangement, the neck in question serves to support the burner box Within the casing. The outer end of the neck 10 is provided with an inwardly extending flange 13 having on its outer face a rib 14 located atthe inner edge of said flange and received in a groove 15 on a door 16, the latter being hinged at 17 to said flange for giving access to the burner 18 in the box 6. The center of door 16 is preferably provided with an isinglass view opening 19 whereby the condition of the burner flames may be seen.

The burner 18 (preferably of the gas type) is provided with a fuel supply line 20 having an air mixer 21 located within the box 6, sothat there is no danger whatever of fumes from the garage being drawn into the burner, the box in which this burner is located, being free from communication with the casing 1 and having only a single flange 11 contacting with the outer casing 1 and having a continuation 23 leading to atmospheric air will be taken into the device to supply the necessary oxygen to the burner.

For carrying off the products of combus-,

tion, a zigza outlet pipe 24 is provided, this pipe being referably formed of a plurality of ti ht y connected elbows and pipe sections a1 located in the casing 1, the rear end of the pipe 24 being provided with a nipple 25 which extends through an open ing 26 in the rear side of the casing, said nipple serving as means for attaching a pipe 27 which leads to the exterior of the building in any suitable manner.

For the purpose of preventing any possible tilting of the burner box 6 around the neck 10, and for holding said box in spaced relation to the side walls 28 of the casing 1, the front end of said box is provided with vertically disposed lateral flanges 29 which abut said walls as featured in Fig. 3. Particular em basis is laid upon the provision anges and the novel support of the burner box 6 by means of the neck 10,

85 the exterior of the garage so that free. V, i

'-'since these features are extremely simple and inexpensive, yet are adequate for obtaining the required results.

When the heater is properly installed, the burner 18 will highly heat the burner box 6 and the outlet pipe 24., with the result that the air rising through the casing 1 will absorb such heat to maintain the temperature of the garage sufliciently'high to prevent freezing of the water in the radiator and to insure easy starting. Since the oxygen for the burner is supplied totally from the ex-- terior of the building and since the air mixer 21 is located in the burner 6, thereis no possibility whatever of any combustible fumes from the garage coming in contact with said burner and causing trouble of any character.

Since probably the best results are obtained from the several specific details shown and described, these details are preferably employed, but within the scope of the invention as claimed, numerous minor changes may well be made.

We claim:

1. A garage heater comprising a rectangular substantially flat vertlcally disposed casin open at itstop'and bottom for free circu at1on of air, one end of said casing having an opening therein, a relatively small burner box in one lower corner of said casing and having one side' formed with an opening, said sideof the burner box contacting with said end of the casing and-the two openings being alined, a short tubular neck 7 lpassing through the alined openings and 'avmg outstanding flanges contacting respectively with the outer side of the casing and the inner side of the, burner box, a burner in said burner box having an air mixer located therein, a movable closure fior the outer end of said neck to permit lighting of said burner, an air su ply pipe passing through the end wall of the easing opposite the aforesaid/end wall and .ex--

2. A garage heater comprising .a casing open at its top and bottom and having an opening 1n one side, a relatively small burner box in said casing-having one side contacting with said side thereof and formed with an opening alined with said first named opening, and I a hollow neck passing through said alined openings, and having flanges contacting with the outer face of the casing and the inner face ofthe burner box to support the latter from the former; together with a burner in said box, a closure for the outer end of said neck, an

air inlet for said burner box, and an outlet for the products of combustion, said outlet passing through said casing.

3. A structure as specified in claim 2 and vertical flanges pro ecting laterally. from said burner box and contacting with two, opposite sides of said casing to prevent tilting of said 'box and to hold the same in spaced relation with said sides of the casing. p i In testimony whereof "we have hereunto set 0ur hands in the presence oitwo subscribing witnesses.
